APPARATUS FOR GOLORING PAPER.

SPECIFICATION forming part of Letters Patent No. 395,257, dated December 25, 1888.

Application filed September 24, 1887. Serial No. 250,539. (No model.)

To @ZZ whom, t may concern:

'Be it known that I, AUeUsTUs A. YERKES, a citizen of the United States, and a resident of Philadelphia, Pennsylmnia, have invented an Improved Apparatus for Coloring Paper, of which the following is a specification.

)Iy invention is designed principally for the production or mam'iiacture of wall-paper; but it may also be used tor the production or manufacture ot other papers or fabrics which have to be colored on one or both sides.

My invention is more espeiiially usei'ul vfor grounding wall-paper-that is, applyinj.;` a ground or body color to one side ot' the web of paper which is to be used tor wall-paper. Under ordinary circumstances this grounding ot' the wall-paper is done in thc wall-paper factory ali'ter the paper has come from the paper-mill; but the grounding ol the paper in the wall-paper Vfactory is soniewhat expensive, owing chietly to the time and large space required for the drying of the color applied to the paper. 'In order to ground the paper in a more economical manner, I provide the ordinary paper-making machine with an attachment b v which the ground color may be applied io the web ot' paper as it is passing over the drying-cyliuders, and the drying' of the color is accomplished simultaneously with the drying ot' The web ot' paper in the paper-making nunidiino. [5y `this moans the separate drying .-'tppliances and the long` space occupied by them in the wall-paper factory are dispense-al with and time and labor economixed.

It has been hcrelot'orc proposet'l to employ coloring devices in coi'lnection with the drying-cylinders ot a paper-making machine; but the coloring` devices proposed have not been of a character practically available for the groundin of wall-paper, because the said devices would not give that even and uniform distribution of the color which is absolutely necessary in applying the ground or body color to wall-paper.

I-n the accompanying drawings, Figure l is a side elevation ot' the drying-cylinders ot' an ordinary paper-making machine provided With my improvement-s, there being illustrated in connection with the drying-cylinders pressing and calendering rolls and the cutting or slitting machine. Fig. 2 is a side elevation, partly in section, of a portion of the drying-cylinders with my improvei'nents applied thereto. Fig. 3 is a plan vienT oi' the same; and Fig. t is a transverse section on the line l 2, Fig. 3.

A is the frame ot the paper-making machine, and B B are the drying-cylinders around which the sheet or web of paper a passes as guided by the endless vapron or blanket t; in the usual manner. Ata suitable point in the traverse ot' the paper I introduce my coloring appliances, and in the present instance I have shown these appliances as arranged over the drying-cylinders so that the sheet of paper, instead ot passing directly to the fifth cylinder :from the fourth, rst passes to the coloring appliances and then returns t0 the remainingI drying-cylinders ot the serics to complete the drying of the paper simulta` neously with the drying ot' the applied color. As illustrated more fully in Figs. 2, 3, and 4, these coloring devices are carried by a frame or side frames, D, which maybe removably mounted on the side frames of the dryin g-cylin ders. 0n these frames D is mounted a coloring table or surface, E, having at opposite ends rollers e, over which `passes an endless blanket, e. Above the front end of this table is mounted an elongated transverse color-box, T, preferably closed at the top by a movable lid, f. Along the under side of the trough is a row of outlet-openings or, preferably, spouts, j, which may be closed by a valve or valves, lo, Figs. 3 and 4f. Immediately underneath these spouts or other outy lets is arranged a transverse rotary brush, G, which is adapted to rotate with its under side in contact, or nearly so, with the paper as the latter passes over the coloring-table.

lTithin the color-box is a rotary stirring brush or paddle, d, to keep the color uniformly distributed throughout the boX. At points along the length ot the table are arranged transverse reciprocating brushes H, for

the proper distribution of the color which has been thrown onto the paper by the distributin g-brush G. Motion may be applied to these several brushes by any suitable means and in the present instance I have shown the rotary brushes as driven by pinions from the gear-Wheels of the drying-cylinders.

The reciprocating brushes are driven by IOO eccentrics 7L on a shaft, 7L', to which rotary motion may be transmitted by bevel-gearillg or otherwise from'the geai'\\'l1eels of the dry ing-cylinders. By preference the several reciprocating brushes are caused to move at speeds differing from each other by making the eccentrics h of different sizes.

Following on the coloring table or surface, and as a continuation thereof, is a heating-surface composed of heating-pipes within an endless belt or apron, J, passing around suitable rollers, J', mounted in suitable bearings in the frames I). In the space left between the bottom and the top li.1e of this apron are the heating-coils K.

The operation of these devices is as follows: The web of paper, asitleaves the fourth cylinder B, partially dried, passes from its giiide-roller 2 to the coloring-table and under the coloring-brush G, which distributes the color as it comes from the color-box in a more or less uniform layer over the paper. The paper with the color thus applied then passes beneath the reciprocating brushes H, which lay the color perfectly even to produce a uniform shade or tint over the entire surface of the paper. The paper then passes over the heating-surface formed by the pipes K within the endless apron J, and thence back along the under side ot' the heating-surface to the tension-roller M, which is so mounted in the `frame that it maybe adjusted at either end to get the proper tension on the web of paper to avoid the formation of wrinkles or creases. The paper thence returns to the drying-cylinders of the machine. In the present instance I have illustrated the paper as returning to the sixth drying-cyliiuler B, thus omitting' the li fth cylinder; but, if desired, the paper may be returned to the fifth cylinder, or, in other words, to that cylinder which immediately succeeds the cylinder from which the paper passes to the coloring appliances.

By the time the paper, colored as described, reaches the dryiug-eylinder, to which it returned, the sizing' in the color will have become set sufficiently by the heat from the coils K to prevent the color from beingl offset onto the succeeding dryiiig-cylinders, which complete the drying of both the color and the paper as the web passes around them.

As will be seen on reference to Fig. l, the web of paper passes from the drying-cylinders, as usual, to the pressing-rolls R, and thence to the calender-rolls P.

By suitably preparing` the color the paper will be so polished by the caleiulering-rolls as to produce the satin iinish for which heretofore a separate polishing-machine has been employed.

In connection with the machine as provided with my coloring appliances I may use the cutting` or slitting machine S, whose cutters are adjusted to trim off the edges of the paper, and also to cnt the paper longitudinally, it' double width is made. By this means the roll of paper as it leaves the cylinder is not only grounded, but is also trimmed at the edges, so that it may be hung` on the walls without further trimming by the wall-paper manufacturer or paper-hanger.

I claim as my invention l. The combination of the drying-cylinders of a paper-making machine with a coloring table or surface, the liquid-color-supply trough having valved outlets, a rotary brush immediately under the latter, and additional colei'- distributing brushes, substantially as described.

2. The combination of the drying-cylinders of a paper-making machine with a coloring table or surface, a liquid-color-supply trough having valved outlets, a rotary distributingbrush immediately below the latter, and reciprocati ng brushes over the coloring-surface, substantially as specified.

3. The combination ot the drying-cylin ders of a paper-making machine with a coloring ta ble or surface, a color-trough having` a row of valved outlets, a rotary distriluiting-brush beneath the latter, and transverse reciprocating brushes over the coloring-surface, substantially as described.

4. The combination of the drying-cylimlers of a paper-making machine with coloring appliances and a heatingsurfaee between the coloring appliances and the drying-eylinders, to which the colored paper is to pass, all substantially as described.

5. The combination of the drying-cylinders of a paper-makingl machine with a coloring-table and color-distrilnlting brushes and heating-pipes above and below which the web of paper passes from the coloring appliances to the dryiug-eylinders, all substantially as described.

o'. The combination of the drying-cylinders of a paper-making machine, a coloring-table, an endless apron passing over the same, and color-di. ributing brushes with heating-coils, an endless apron passing around the coils, and a tension-roller, all substantially as set forth.

In testimony whereof I have signed my name to this speci tication in the presence of two subscribingl witi'lesses.
